Consider the chemical reaction 2nh 3(g) image n 2(g) + 3h 2(g). The equilibrium is to be established in a 1. 0 l container at 1,000 k, where k c = 4. 0 × 10 –2. Initially, 1,220 moles of nh 3(g) are present. Estimate the equilibrium concentration of n 2(g).

The solutions to the inequality y ≤ 2x − 4 are shaded on the graph. which point is a solution? p

Heights of men on a baseball team have a bell-shaped distribution with a mean of 177 cm and a standard deviation of 6 cm. using the empirical rule, what is the approximate percentage of the men between the following values? a. 159 cm and 195 cm b. 165 cm and 189 cm a. 89% of the men are between 159 cm and 195 cm. (round to one decimal place as needed.) b. 89% of the men are between 165 cm and 189 cm. (round to one decimal place as needed.)
